Repair of modern electric heaters at home

[shapanwwuom]

The question of how to repair household heaters of various types is asked quite often, since these devices are used everywhere and are not insured against various types of breakdowns.

Modern heaters, whether convectors, infrared or oil, are made according to uniform principles, but can differ radically in layout and engineering solutions. Let's consider a certain universal scheme for dealing with malfunctions, focusing on the key features of individual classes of devices.

Basic safety rules
It is always important to remember that home heaters are powerful devices that operate on a high-voltage network. Therefore, safety precautions are the first thing to follow when repairing an electric heater:

It is essential to de-energize the device by removing the power plug from the socket.
A backup power supply must be provided. In addition to the poland telegram data socket into which the heater was plugged, another one will be needed, or an extension cord with reliable contacts and a wire designed for the corresponding power of the device.
Only tools with insulated handles are used.
Do not handle the disassembled heater with wet hands.
To check the circuits of the device, special measuring devices must be used. Homemade "ringers" are unacceptable.
It is necessary to ensure good lighting of the workspace.
And the main thing that needs to be done when repairing home heaters is to proceed from simple to complex, take your time, and before performing any operation, think about whether there are means to eliminate its consequences.

Basic breakdowns
The first thing to check is the integrity of the fuses . They may burn out due to increased voltage in the socket or a sudden reset of parameters. Therefore, checking and replacing the fuses, if they are available, is the first reasonable step.


A common cause of electric heater failure is described as a "circuit break." Roughly speaking, energy does not circulate along the calculated circuit.
